Abstract

Uso de una película multicapa como cubierta dorsal de un módulo fotovoltaico, en donde la película multicapa se compone de las siguientes capas: a) una capa orientada hacia la célula solar a base de una masa de moldeo que contiene una proporción de poliamida de al menos 35% en peso, referido a toda la masa de moldeo, c) una capa central que se compone de una masa de moldeo que contiene una proporción de polipropileno de al menos 35% en peso, referido a toda la masa de moldeo, así como e) una capa dispuesta hacia el exterior a base de una masa de moldeo que contiene una proporción de poliamida de al menos 35% en peso, referido a toda la masa de moldeo, en donde la adherencia entre las capas conformes a a) y c), así como entre las capas conformes a c) y e) se genera mediante una medida que se elige de 1. presencia de polipropileno con una concentración de grupos anhídrido de ácido suficiente para la mejora de la adherencia o de una poliolefina funcionalizada compatible con polipropileno que proporciona grupos suficientemente funcionales para la unión a las capas de poliamida, en la masa de moldeo de la capa conformes a c), 2. incorporación de una capa de promotor de la adherencia b) entre las capas conformes a a) y c) y una capa de promotor de la adherencia d) entre las capas conformes a c) y e), que se componen de un polipropileno que contiene grupos anhídrido de ácido que se incorporaron, mediante reacción térmica o en los radicales del polipropileno con un anhídrido de ácido dicarboxílico insaturado, un ácido dicarboxílico insaturado o un éster monoalquílico del ácido dicarboxílico insaturado.Use of a multilayer film as the back cover of a photovoltaic module, where the multilayer film is composed of the following layers: a) a layer facing the solar cell based on a molding mass containing a polyamide ratio of at least 35% by weight, based on the entire molding mass, c) a central layer consisting of a molding mass containing a proportion of polypropylene of at least 35% by weight, based on the entire molding mass, as well as e) a layer disposed outwardly based on a molding mass containing a proportion of polyamide of at least 35% by weight, based on the entire molding mass, wherein the adhesion between the layers conforming to a) and c), as well as between the conforming layers ac) and e) it is generated by means of a measure chosen from 1. presence of polypropylene with a concentration of acid anhydride groups sufficient for the improvement of adhesion or of a functionalized polyolefin compatible with po Lipopropylene which provides sufficiently functional groups for binding to the polyamide layers, in the molding mass of the conforming layer ac), 2. incorporation of an adhesion promoter layer b) between the conforming layers aa) and c) and a adhesion promoter layer d) between conforming layers ac) and e), which are composed of a polypropylene containing acid anhydride groups which were incorporated, by thermal reaction or in the polypropylene radicals with an unsaturated dicarboxylic acid anhydride, an unsaturated dicarboxylic acid or a monoalkyl ester of the unsaturated dicarboxylic acid.
